all 7mm it 4n concern Be it known that I, J EDWIN Enroson, a citizen of t he Uiiite'd States, and ZLIGSI- State of California, have invented "a new and useful Noiseless l loat Valve; of which the following is a specification.

Myinvention relatesto a valve iter con trolling the fiow'of water to-a 'flush* tanlzc. "An object of the "invei'ition'is tic-provide a "valve ofthe characterdescribed which will enahlethe *water to he introduced into the tank without the objectionable noise. Another object is ee-provide a valve having the "foregoing" feature, which allows of the tank being filled very quickly.

Affurther "object is "to provide a valve "of the chara'cte r described which is extremely simple and economical in construction. 1

The invention possesses other objects and features of advant ge-some of which, with the "foregoing, will be -set forth in the following "description of the preferred form of my invention which 'is illustratedinthe drawings accompanying andj-forlnin g part of l the specification. It is to 'he understood thatj I do i not limit myself to 'the showing de by the sai d drawings and description, as l may adopt variations of'th'e preterred foriirwithhi the scope of iny invention a-s set forth in the c'laiins.

Refei:-1-ing to i said drawings: Figure 1 is a sectional 1 taken 'through a "flush itanl: showing the valve in elevation.

Fig-zine 2 is a longitudinal sectionalview 1 of the valve and a portion ofthe associated parts. 7

As illustrated the valve is arranged in a llush tank -"2 *and is combined with the 1 flanged nipple 3 which extends through the bottonrof the tank and connects with the feed -pipe. 'Sec'ured tothcnipple such as by screw threaded engagement is a valve housingfi to the discharge end t of which is fitzed a'n outlet pipe 7. The latter sup ports the head 8 11 13011 which is "mounted the lever mechanism 9 connected to the The nipple 3 is provided with an opening 12 which communicates with the chamber 13 within the casing and is adapted to be closed by a valve 14 normally resting on the seat 15. The valve 14 is provided with a stem 17 which extends through the casing 5*and pipe 7 "and into the head 8 where it is adjustably secured to a cap 18 which is 'slidably inounted in dent of Oakland, *county of Alameda, and

the-head and is slotted for engzi genient with oneoff thehloat actuated leversS). hen the is in an elevated position the levers exert a downward pressure on the cap and cause the valve to be firmly held upon its seat; thereby cutting oiPthe supply of water -tothe tank.

I-SI-idabiy inountedon the stem and enclosing the valve v 14 is Fwhat *in'ay he termed =a-seco1idary valve 21. Thelatte-r is in the for of a shell or inverted cup, the base 22of'uvhichis ada pted to rest on a seat 23 sur'i'o mdingftheseat of the valve 14.

A spring 24*i nte'rposed between the top of the valve 21 and the web -25 in the interior of the 'ho'iis-ing functions to resiliently remain the- 'second valve against its seatJW'hen the 'valve21is seatedit virtually forms a substantially sealed chamber in which the vaive le and i-tsentire'seat are contained.

ivhei -both valves "are seated the top of the valve is spaced from the adjacent ertienyof th'e fVtlVe 21, thereby allowing the fir's'tnained valvetobe raised from its seat a limited ainount without afiecting the other valve.

In the operation-of the apparatus, upon the suflicient loweringof the level of the wat r withi n the tank, andthe consequent descent otFt'hefloat, the valve 1 1 is raised until-it "abuts against the valve 21, the weight of the float being inerely' suflicient to cli-spl aces aid firstv alve. As soonhowever a s the opening 12 i'suncovered, the water from the supplypipe fills the chamber within {the valve 21 and the pressure thereof L causes-the said valve to he raised from its seat, whereupon the water passes into the f chamber-13 a n'd thei'ice escapes into and fills the outlet pipe 7. The pipe 7 is substantially closedl'by the lie'ad'S- so that the water 'is forced to exit therefrom through the more or less restricted openings 26 preferably forined belowthemiddle ofthepipe. Upon discharging from the pipe "T the watershters the=-anntila1"chambers27 and 28 in the order nained *and* thence into i the tank. The

large part of its energy in impinging against the walls thereof; furthermore, due to the water being forced to pass through the apertures 26 and subsequently caused to traverse the long path through the chambers 27 and 28, still more of the waters energy is lost, so that by the time it enters the tank it is in a more or less quiescent condition, and the tank is allowed to fill comparatively noiselessly.

A small space is preferably provided between the stem and the head 8 so that sufficient water may escape into chamber 34: from whence it may be discharged through the pipe 35 for refilling the closet bowl (not shown).

I claim:

1. A float-valve for flush tanks, comprising a primary valve adapted to be operated by the float and to normally close the water inlet passage to the tank, and a secondary valve enclosing said primary valve and its seat adapted to be unseated by the force of water to which it is subjected upon the unseating of said primary valve by the float.

2. A valve for controlling the flow of water to a flush tank, comprising a valve normally closing the water inlet passage to said tank and adapted to be unseated by the depression of a float within said tank, a second valve surrounding said first valve and comprising a shell mounted for longitudinal movement with respect to said first valve and provided with a seat completely surrounding the seat of said first valve, and a spring normally resiliently retaining said second valve against its seat.

3. A valve for controlling the flow of water to a flush tank, comprising an inlet passage and a primary valve normally closing said inlet passage and adapted to be unseated by the depression of a float in said tank, a stem extending upwardly from said valve and connected to said float, a shell-like valve slidably carried on said stem open at its base and enclosing said primary valve and adapted in its seated position to form a sealed chamber, and means normally resiliently retaining said shell valve in its seated position.

4;. A valve for controlling the flow of water to a flush tank comprising an intake pipe and a chamber having openings respectively communicating with the interior of the tank and with said intake pipe, a valve arranged in said chamber and normally seated over said second opening, a stem for said valve extending through said first opening and adapted to be connected to a float within said tank, a second valve slidably mounted on said stem and enclosing said first valve, the base of said second valve being open and adapted when the valve is seated to surround said second opening and substantially seal the intake passage from the chamber independent of said first valve, and a spring adapted to retain said second valve seated until a limited displacementof said first valve has been effected.

5. A valve for controlling the flow of water to a. flush tank, comprising an intake pipe and a chamber having openings respectively communicating with the interior of the tank and with said intake pipe, a tubular perforated member having one end leading from said first opening and having a head on its other end, a plurality of tubular members surrounding said first tubular member but spaced therefrom, and each other, the alternate opposite ends of said members being closed so as to provide a circuitous path through said members, and a valve in said chamber normally seated over said second opening and having a stem extending through said tubular perforated member.

6. A valve for controlling the flow of water to a flush tank comprising an intake pipe and a chamber having openings re spectively communicating with the interior of the tank and With said intake pipe, a valve arranged in said chamber and nor mally seated over said second opening, a stem for said valve extending through said first opening and adapted to be connected to a float within said tank, a second valve slidably mounted on said stem and enclosing said first valve, the base of said second valve being open and adapted when said valve is seated to surround said second opening and substantially seal said intake passage from the chamber independent of said first valve, a spring adapted to retain said second valve seated until a limited displacement of said first valve has been effected, a tubular perforated member leading from said first opening and tubular members surrounding said first tubular member but spaced therefrom and each other, the alternate opposite ends of said members being closed so as to provide a circuitous pat-h through said members.

In testimony whereof, I have hereunto set my hand at Oakland, California, this 10th day of December, 1921.

J EDWIN ERICSON.
